XF = 0.5 , F =1000000 LB MOL/DAY =1000000/24 = 41666.67 LB MOL /HR
FORMULA -
Xbi = XFi /1+f (Ki -1)
XB = 0.949 /1+ 0.5 ( 2.85 -1) =0.949 /1+0.5 ( 1.85 ) = 0.949 / 1+0.925=0.949 /1.925=0.493
YB= Ki* xbi = 2.85 * 0.493 =1.405
FOR C2 COMPONENT -
Xbi = 0.042 /1+ 0.5 (0.36 -1 ) =0.042 / 1 + 0.5 * ( - 0.64)
